- Dev Log #4 — The Return - 10 June 2026
Hi!Yes, yes, you read that right — the developer is still alive, and the game is still actively being developed )There haven't been any news updates over the last four months, but development has been moving forward the entire time.New LanguagesAs promised earlier, the game now includes support for two additional languages: Ukrainian and Dutch.Level 3 ContractsFirst of all, I'm happy to announce that Tier 3 contracts are now complete. They are currently undergoing extensive testing and bug fixing.But these aren't just bigger contracts. Their development also marked the beginning of a new construction system, which I'll discuss further below.New Construction SystemOver the past few months, I have spent a lot of time reviewing player feedback about the current construction system. Many players pointed out that some aspects of it were not as intuitive as they could be and would benefit fro…
- Dev Log Schedule Update - 2 February 2026
Hi!I’d like to briefly talk about the future format of the dev logs.Initially, I planned to publish a development diary once a week, but in practice it became clear that the results of a single week of work are not always noticeable or interesting from the outside.Sometimes several days can be spent on things that are important for the game but are almost invisible to players. This is a necessary part of development, but it’s difficult to dedicate a separate dev log entry to it.That’s why dev logs will be published less frequently going forward — as genuinely noticeable updates appear, but at least once a month.Development itself continues as usual — it’s just that not every working week has something worth covering in a separate post.When new mechanics, content, or important changes are ready, I’ll definitely share them in dev logs and also cover them in a separate update-related news…
- New localizations - 31 January 2026
У грі реалізовано підтримку української мови, яка стане доступною в наступному великому оновленні. Ondersteuning voor de Oekraïense taal is al geïmplementeerd en wordt beschikbaar in de volgende grote update.
- Dev Log #3 — Knock, knock. Who’s there? Update 0.4. Please wait a bit - 26 January 2026
Hi!As you can probably tell from the title, the update release is taking a bit longer than expected.The new contracts turned out to be more complex to develop than I initially anticipated, and I’m still working on them.I expect to finish this update — at least bring it to a full testing stage — within the current week.I deliberately focus more on testing at every stage of development. This extends development time for updates, but results in more stable and well-designed content.There’s no real point in once again listing everything that will be included in this update, so this time I’d like to talk a bit more about the next update instead.What’s planned for the next updateIn the next update, the user interface will be completely reworked.Main planned changesUnified UI styleAll user interface elements will be redesigned in a single, consistent style.Current UI style:Upcoming UI style:Un…
- Dev Log #2 — Level 3 Contracts and New Elements - 19 January 2026
Hi!Here’s the next entry in the developer diary )What was done this weekThis week I didn’t manage to do quite as much as I originally planned, but there is still clear progress — and it’s noticeable.Five new layouts for level 3 contractsI’ve finished creating all five layouts for the new bunkers. The total area, room layout, and required furniture have all been defined.Key features of level 3 contracts:multi-level bunkerslarge total areasnew room typesnew furnitureNew construction elementsTo support double-height spaces, railings of different lengths have been added:New inter-floor slabs were also added:intermediate floor 0.5x0.5 mintermediate floor 0.5x1 mintermediate floor 0.5x2 mNew room typesLevel 3 contracts will introduce several new room types:gymlounge roomrec roomworkshoplaundrytrash roomNew furnitureNew furniture items have been added for the new rooms, as well as for some exi…
- Dev Log #1 — Introduction and the Road to Version 0.4 - 12 January 2026
Hello everyone!I guess it’s finally time for us to get acquainted )My name is Alexey, I’m the solo developer of Bunker Constructor Simulator, and I’ve decided to start a small developer diary. The plan is simple — short updates once a week, so you can follow the development and be sure that the project is alive and the developer is still around )What was done this weekAt the moment, I’m on the home stretch (at least I really hope so) toward the first major update — version 0.4, which will introduce a new district and new contracts.New district — Bluepoint RidgeThe road past the gas station now leads not uphill, but into the second district.The district itself is almost finished: houses, streets, and even fences are already in their places.Because the world size was increased, I had to slightly modify the landscape, mainly in the area between the two districts.Over the next few months, I…
